Blackbeard's sword found?

It's likely Edward Teach didn't need much to scare his enemies. After all, the notorious pirate better known as Blackbeard boasted a thick mass of facial hair so intimidating that it got immortalized in history.

But archaeologists now suspect they've found one more clue behind the pirate's menace: what could very well be Blackbeard's sword, or at least part of it. National Geographic published photos released by a team that has for more than a decade been excavating the Queen Anne's Revenge, which was Blackbeard's flagship until it ran aground in an inlet off the coast of North Carolina in 1718.
